no. 1 Embodiment approach >

[0036] figure 1 It is a schematic cross-sectional view of the first embodiment of the glass laminate of the present invention.

[0037] like figure 1 As shown, the glass laminated body 10 is a laminated body having a layer of a support base material 12 and a layer of a glass substrate 16 with a silicone resin layer 14 interposed therebetween. One side of the silicone resin layer 14 is in contact with the layer of the support base 12 , and the other side is in contact with the first main surface 16 a of the glass substrate 16 .

[0038] The two-layer portion formed by the layer of the support base material 12 and the silicone resin layer 14 reinforces the glass substrate 16 in a member forming process for manufacturing members for electronic devices such as liquid crystal panels. In addition, the two-layer part which consists of the layer of the support base material 12 and the silicone resin layer 14 manufactured beforehand for manufacturing the glass laminated body 10 is ...

[0185] image 3 It is a schematic sectional view of 2nd Embodiment of the glass laminated body of this invention.

[0186] like image 3 As shown, the glass laminate 100 is a laminate having a layer of a support base 12 , a layer of a glass substrate 16 , and a silicone resin layer 14 interposed therebetween.

[0187] image 3 The glass laminate 100 shown is the same as the above figure 1 The glass laminate 10 shown is different in that the silicone resin layer 14 is fixed on the glass substrate 16, and the glass substrate 20 with the resin layer is directly bonded to the support substrate 12 with the silicone resin layer 14 in the glass substrate 20 with the resin layer. They are laminated (closely bonded) on the supporting base material 12 in a peelable manner. There is a difference in the peel strength (that is, the stress required for peeling) between the fixation and the peelable adhesion, and the fixation means that the peel strength is higher than that of the adhes...

[0235] Hereinafter, although an Example etc. are used and the present invention is demonstrated concretely, this invention is not limited to these examples. In addition, in this production example, evaluation of curable organopolysiloxane was performed according to the items and methods shown below.

[0236] (1) Analysis of bonding state of silicon atoms in curable organopolysiloxane (proportion of T units)

[0237] Using NMR analysis equipment (solution 29 Si-NMR: JEOL RESONANCE Co., Ltd. make, ECP400) The ratio of T1-T3 was calculated|required.

[0238] The specific solution of T1~T3 29 The peak area ratios of Si-NMR were obtained respectively. The measurement conditions were set as follows: a pulse width of 20 microseconds, a pulse repetition waiting time of 30 seconds, and an accumulation count of 256 scans. Add 0.1wt% of Cr(acac) as a relaxation agent to a solution prepared with a concentration of 30wt% using toluene as a solvent 3 . For the reference of the chemica...

Abstract

Provided is a glass laminate wherein a glass substrate is able to be easily separated even after a high-temperature heat treatment, and wherein decomposition of a silicone resin layer is suppressed. A glass laminate which is provided with a supporting base layer, a silicone resin layer and a glass substrate layer in this order, and wherein: a silicone resin in the silicone resin layer has an organosiloxy unit represented by formula (T3); the ratio of the total organosiloxy units represented by formula (T3) to the total organosiloxy units is 80-100% by mole; the molar ratio of organosiloxy units (A-1) represented by formula (T3) wherein R is a phenyl group to organosiloxy units (B-1) represented by formula (T3) wherein R is a methyl group, namely (A-1):(B-1) is 80-20:20-80; and a specific peel strength relation is satisfied. T3: R-SiO3 / 2 (In the formula, R represents a phenyl group or a methyl group.)

Description

technical field [0001] The present invention relates to a glass laminate, and more particularly to a glass laminate including a specific silicone resin layer. Background technique [0002] In recent years, devices (electronic devices) such as solar cells (PV), liquid crystal panels (LCD), and organic EL panels (OLED) have been reduced in thickness and weight, and glass substrates used in these devices have also been reduced in thickness. When the strength of the glass substrate is insufficient due to thinning, the handling property of the glass substrate decreases in the manufacturing process of the device. [0003] Recently, in order to cope with the above-mentioned problems, a method has been proposed in which a glass laminate in which a thin glass substrate and a reinforcing plate are laminated is prepared, and components for electronic devices such as a display device are formed on the thin glass substrate of the glass laminate, and then the The substrate separates the ...
